"We leave for Beacon tomorrow. Everyone should be up and running on time." Itachi ordered as the four of them were strolling through the city of vale.

The city was bustling with activity as usual. The recent increase in crime rates had resulted in increased vigilance in the area. The police presence was higher than usual. Some people were minding their own business while others were engrossed in some activity. A few section of lowlifes were busy insulting the faunus who were among the populace. Dust prices had shot up to the point that some people found it too expensive to acquire. But that was of no significance to the four teenagers that strolled through the streets.

"Yea Yea, we get you" Zack was the only one to respond. Gohan knew Itachi never referred to him when he spoke about things like these as he was never late.

The others were a different matter. Zack basically loved getting late and messing around mostly annoying Acno.

While Acno did things in his own pace. Many a times they were behind schedule because Acno was not the one who was prepared to abide by the constraints set by humans and faunus. He would purposely be late and many did not have the guts to question him. To make up for this, Itachi and Gohan sometimes lied about the time of reporting even upto several hours.

"Can't we just walk there? Why do we have to take a stupid airship?" Acnologia was not very pleased with the idea of taking an airship. He might have been the Dragon King, but motion sickness was another matter. All the times he had taken one before, he had been the centre of attention of everyone present and Zack who was always beside him in these dire times did not help the cause. But since the option of flying on his own did not exist anymore, there seemed no other alternative most of the time.

"It's been sometime since I saw you make your puke face. Lol. I am going to enjoy myself tomorrow." Zack couldn't' stop the muffled laughs that escaped him. For some reason the former first class soldier would never miss a chance to take a dig at the dragon slayer. He enjoyed it much to the latter's annoyance. Now, even after so many broken bones and bruises it did not cease.

The dragon slayer did not find giving any form of reply, worth wasting his time over. He was better at settling things with his fists and not words. Unlike others, the three of them were given absolute freedom. If it were anyone else and things wouldn't go so good.

But Zack wouldn't stop "remember that one time, he puked all over me. That was really gross."

"That's because you kept poking his belly and cracking horrible vomit jokes" Gohan retorted as he put his hand over the dragon slayer's shoulder trying to calm him down before the banks of patience broke and he sounded the bell for a destruction spree.

Acnologia just face palmed and continued to walk to some stupid clothing store as he described it, Zack found to be amusing. Honestly, he never cared about appearances. He still wore the same attire he had worn since centuries ago. The same high collared, black cloak which bore his draconian markings, sharp red claws around his neck, a sash around his waist, a gold arm ring tightened around his right upper arm, and baggy black pants. This strange attire coupled with his dark blue hair was attracting unwanted attraction towards the Black Dragon. Some giggled at his appearance, others gave him a look of being some lunatic, and some took an expression of fear, while some others actually seemed to take a liking to it. The Dragon king patiently bore through these unwanted attention. These new situations had taught him to improve his level of patience. Unlike the old times where he would raze the city to the ground.

The racial tension, so high in the air. These did not interest the Dragon Slayer in the slightest and he never felt the need to concern him with these matters. Wasn't it the natural rule? The strong will always oppress the weak. That is what he believed in. In any world, only strength mattered.

The black dragon of the apocalypse felt disgusted at the thought of being surrounded by humans. Unlike his comrades, he did not prefer interaction with anyone else. Either the solitude of the mountains or the forests or when they were in cities, the quietness of his room. This was what he liked. The sights of the city always brought back feelings of rage and hatred in him. It took him back to the times of chaos when the dragons ravaged his city and how helpless he felt during those times of darkness.

X-X

The Dragon King knew he was different from the other three. He wasn't a hero and never wanted to be one. He did not fight for the sake of others, only for himself. His sole objective was to reap his vengeance. Once he had made a promise to a dying girl whose life he was unable to save. He promised her that he would eliminate all the dragons in Earth land. But even then that promise was made only to fortify and enhance his quest for vengeance.

The dragons had taken everyone and everything he treasured and held dear from him. The flying beasts razed his city to the ground. All he remembered was the chaos, panic and agony around him. His friends, his family everyone killed and eaten by the scaled beasts. Each day witnessed the helplessness and the pitiful plight of his race in front of the dragons. That day, he swore he would attain the power to slay all the dragons. That day, he forsaked mercy from his heart. He let the hatred and rage take over.

Armed with a new found power, he fought and slaughtered countless dragons, never for the cause to save humanity but for his reckoning and to satisfy and feed his hatred. He never cared about anything other than his revenge. He lived for the sole purpose of slaughtering the dragons that once terrorized his dream. In time, this vengeance ate away at his heart and finally consumed him. Finally, he turned into the one thing he so loathed and despised. He himself had turned into a dragon. The Black Dragon of the Apocalypse.

Dragons who were against the humans and those who sided with the humans, he killed them all without mercy. But unlike, his legends said, he was not initially interested in killing humans, only the ones that stood in his way. The humans rose against him to protect the dragons who had sided with them. Blinded by the blood red flames of vengeance and corrupted by the sheer power that flowed through his body, he killed every human who opposed him. In time, human life became nothing to him. He did not consider humans anything more than insects whose lives were insignificant. Having witnessed all the terrible vices of the human kind, he only regarded them with contempt. Now, he had become something more than humans and even more than dragons. He had become the Dragon king. The Black Dragon of the Apocalypse. The dragon who devoured all magic. From there onwards the reign of the terror of Acnologia began. Every time he would appear, it was signified as the end of an era.

He had the power to rule the world if he so wished, he chose not to. Only Dragons and Dragon slayers piqued his interest. He would waste his time meddling with a human only if he thought he would pose a worthy challenge. Lowly humans and their affairs did not interest him in the slightest. He hated humanity but considered them unworthy of receiving his hatred. Every human that had threatened him or faced him met the same tragic end. Only one had fought him and lived to tell the tale.

When he met his end in the hands of the fire dragon slayer, somewhere in him he questioned his motives. His nemesis, who fought for the sake of his comrades intrigued him. What fuelled his flames was not the desire to avenge his foster father but the will to protect his family. When he had fallen, he passed on the title of Dragon King to him having finally met an opponent who could defeat him.

But never ever did he regret what he had done. When he found himself in this world, he agreed to an alliance only for his convenience as he found himself returned to his human self, unable to transform into a dragon. He could see the other three was strong maybe even stronger than him, and one other thing he enjoyed was fighting people who could give him a real challenge. His initial motive was that he wanted to obtain information of everything that happened and after that he would challenge them. According to him, only he should remain as the strongest in the world.

But in time he found he could relate his past to that of Gohan. The androids were like the dragons, maybe even worse. But what surprised him was the cause that the saiyan fought for. He did not fight for avenging his fallen friends and comrades but to protect the smiles and happiness of his world. To someone like him who believed people only lived to achieve their selfish dreams, someone like Gohan existing was unbelievable. He sacrificed his entire life for the cause he believed in.

Itachi and Zack too never let revenge guide them. Itachi eschewed everything he had for the sake of his village and his little brother. He still called himself a proud shinobi of the hidden leaf even after all that they put him through.

Zack was hunted by the same organization he dedicated his life to. They abandoned him and even experimented on him. When he had awoken, his motive was not to exact revenge but to meet up with his girlfriend and start a new life along with his friend. One thing, the dragon king admired in him was his attitude of only walking forward putting aside the past. Finally, the soldier gave up his life to protect his friend when he could have easily abandoned him to save his own.

Never in his wildest dreams did he fathom such people existed. People who rose above vengeance and hatred. The humans he knew lived only to fulfil their wicked ambitions regardless of the impact.

In his life he died a villain. When he met his end, people rejoiced at the end of the reign of terror of the Black Dragon. No one remembered him for the person he was before who once fought against the Dragons that terrorized humanity, though it was to satisfy his lust for revenge. It did not affect him. The legacy he left behind would make history remember him only as the Dragon of the Apocalypse.

Still, after all these years, he never regarded the lives of other humans and had no qualms taking one. 7 years had passed since he came to this world. For others, it might be a long time. But for him, who had lived for centuries it only seemed like a few days. But during this time he had grown close to them to the point he would call them comrades and friends, even family. If anyone threatened him or his comrades, he would kill them without mercy or hesitation.

They did not seem bothered by his past. They asked him to consider it as a chance to atone for his actions. Even now, he did not realize why he should atone when he felt what he did was what he ought to do. The other three had always held him back numerous times when he proceeded to take lives. They believed in him to make the right choices.

In time they had changed him. The murderous intent he felt was not that prevalent anymore. Even though he still despised and hated humans and still regarded them as nothing more than weeds one would never bother if stepped upon, he was able to hold back from taking lives casually. He learned to turn a blind eye to mockery from outsiders until it was said straight to his face. Even then, the culprit left with only broken bones and not life threatening injuries. This was not the case for those who threatened his or his comrade's lives. Every time he proceeded to slaughter his adversaries he believed his comrades would be there to stop him.

One other thing he so loathed was humans and faunus who considered themselves to be on equal footing with him. This was the reason, he never let fights drag on though Itachi and Gohan had pleaded with him time and time. His arrogance had diminished not one bit. He still regarded himself superior to the lowly inhabitants of this world. He would never stoop to their level. They should know their place, which was many levels below him

Maybe that was the reason he grew to love his comrades. He did not regard his comrades as humans, saiyans or ninjas or anything. He considered them as his equals. This was why he had learned to care about them. This was why he would do anything to protect them. Their lives were the only lives he treasured. They were to him the family he had once lost to the dragons. These feelings he harboured in his heart was the sole reason he decided to follow them and the lone motive that he had agreed to whatever plans they had hatched for the future. He himself did not have any purpose in life, so he decided to follow whatever path that they had chosen.

"Caps, you have any idea on what that initiation is going to be." Zack cut in between the conversation of Itachi and Gohan.

"I tried digging in but it's kept a real secret. It seems that they change it each year." Itachi replied while his gaze was fixed on the dragon slayer behind him.

"Looks like he's become a lot more patient." He mused to himself. The Uchiha wasn't excepting the Dragon Slayer to turn a blind eye to the gazes that he was getting courtesy of his outfit.

"I really wanted Atlas. They had a lot of pretty girls. Too bad I had to bid adieu to my fan club." Zack went on in his casual goofy tone.

"I told you earlier Zack. I don't really trust Ironwood. He is the sort of person who puts power above everything and prefers a direct approach to things. If he started digging further into us, things might have got a bit complicated. His intentions might be good but I do not approve of his methods."

"Then there is one more reason I didn't tell you guys."

"One more? What is it Uchiha?" Acno questioned the sharingan user now getting interested in the conversation.

Itachi looked around themselves to make sure no one was listening to them. "This Ozpin of Beacon seems to know a lot more secrets about this world than Ironwood. I want to gather all this information from him. But from what I have heard, he is a cunning man with a ton of experience with him. We won't get much from him unless we try hard. So think of this as a way to know more about how we ended up here. We have to gain his trust before we can learn more about things."

Itachi concluded.

The leader of team Izanagi then looked into each of his comrade's faces to decipher their thoughts. He found Gohan and Acno were approving of his action while Zack was still a bit aloof and putting up a clownish face.

"Then again Beacon is the best of the bunch and also must have a lot of pretty girls. So don't go worrying about that. I am sure you would get another fan club soon" The Uchiha sighed to himself before he uttered these words.

Zack gave a cheeky grin as he rubbed the back of his head. Now he was satisfied. One thing he always adored was recognition and acknowledgement. He had quite a fan base back in Gaia and he always enjoyed the attention.

"Don't forget Zack, things would have been normal if both you and Acno didn't go showing off all the time and rubbing many people the wrong way." Gohan added.

"Hey, I was not showing off. Besides it was the Dragon boy who put everyone he faced in the infirmary for weeks." Zack tried to plead his cause.

Gohan turned to see an Acnologia who had already given up from responding.

"But, you were the one who pissed off that Shnee girl that landed us in a hell lot of trouble." The Dragon king cut in now deciding he was not giving up.

"Hey, that's not my fault. She's the one who accepted my challenge."

"She might have but what you did really pissed her off. But if I am honest with myself, I have to say that was really amusing." Acnologia gave out a laugh as he spoke.

Both Itachi and Gohan smirked to themselves while Zack gave a sheepish grin. He didn't know whether that was an insult or a compliment.

Ever since he found out about how his semblance worked, Zack picked up a sort of bad habit of gathering semblances. He was able to copy anyone's semblance and make it his own. His massive aura allowed him to execute and wield that power even better than the real owner.

This habit forced him to challenge the eldest of the Schnee when they were summoned for a mission. She was unaware of what his semblance was and fell into his trap to reveal her semblance to him. Things took a turn for the worst when he started using her semblance against her. Add to that, he had a cocky grin when he did that which signified he had made a fool of her. Next thing he knew she had started flinging 'rich people abuses' at him. Acnologia laughed his mind off while Itachi had to take away Zack before the military specialist made an order to shoot him down. Poor Gohan was left with the task of calming her down. Since that day, she's always had a watchful eye on them hampering their initial idea of keeping a low profile.

"Ok I agree that I might have messed up a bit. But what about that time when tribal man here took down that harbinger" Zack went on not backing down.

"That was clearly understandable. That grimm resembled a dragon and given his past, it's only natural he would want to kill it." Itachi retorted now siding with the dragon slayer.

The dragon king only gave a cocky grin which exuded that he had mo regrets of what he had done and would do it again.

But to be honest, Itachi was lying when he said it was understandable. It was during a field mission along with the entire class that the harbinger appeared. The teachers immediately concentrated on getting the students to safety while frantically requesting for backup. There wasn't any high level hunter capable of taking down the ss class grimm among them. Both Itachi and Gohan tried their best to dissuade the dragon king. But it failed miserably. His hatred towards dragons got the better of him. The harbinger was an ss class grimm that only the best hunters were assigned to take out. Acnologia knocked first knocked out the professor who tried to stop him and went face to face with the grimm, With only three quick strikes of ice element magic, he incapacitated the harbinger before ripping it to pieces with his final attack. The entire class along with their accompanying faculty were witnesses to this act. Whatever plans Itachi hatched to maintain a low profile was ripped to shreds on that day. The attack on the teacher earned him a suspension but from that they day onwards, the dragon king was feared among all the students and even among the professors. It earned him the moniker 'The Dragon Slayer of Atlas". Honestly, he carried that moniker with pride.

"Thinking back, that was the day I had the most fun" Acno burst out cockily.

Gohan and Itachi simply sighed while Zack made some stupid comment about how the harbinger and Acnologia looked alike.

"That aside, don't forget the plan." Itachi announced breaking the mood.

"Me and Zack will stick together during the ride while Gohan is with Acnologia. I am there to stop Zach from hitting on some random girl and showing off. Gohan's task is to prevent anyone from mocking Acno when he experiences his motion sickness. If anything happens, God only knows what he would do to him. Try your best to prevent attracting unwanted attraction towards yourselves."

"After you reach the school grounds, each group will go our separate ways. Try to gather as much information as you can. We will regroup at night and share whatever information we have obtained. After that I will inform you further on the plan."

"But, Itachi what if the initiation is on the same day?" Gohan questioned.

"It won't be." Itachi affirmed. "From all the information that I have gathered, the initiation test is only conducted on the next day"

"Okay then." The saiyan seemed satisfied.

"I repeat once again. DO NOT GO AND PICK FIGHTS OR GO AROUND CAUSING TROUBLE DURING THE AIRSHIP RIDE AND ALSO AT THE ACADEMY." The Uchiha ordered with his eyes fixed upon the Former Soldier and the Dragon Slayer while stressing on the last sentence he spoke.

Acno scoffed in reply while Zack gave him a thumbs up.

"Alright we get you caps. Let's get to that store already." The soldier declared before he walked on in front. The other three merely followed him.

From the next chapter, we go into the main story.

Before that let me ascertain the character of all four of them.

GOHAN here will not be as cheerful and outgoing as his past counterpart. This is because he died before he could destroy the androids plaguing his world. I am not including the Xenoverse 2 storyline where he meets future Trunks here. So, he would still be Gohan but a bit more reserved because he still harbours doubts in his hearts regarding the fate of his world.

ITACHI would be like the Itachi before the Uchiha massacre. The kind and caring Itachi. He died without regrets and so only looks to walk forward in his new life. He deeply values his new friends and would do anything to protect them.

ZACK would be the normal Zach. Armed with a positive attitude and is always ready for work. He still has that energetic personality and short attention span. Like in the beginning of crisis core, he is sociable and easily befriends almost everyone. He is flirty with women, a bit of a show off and extremely protective of his friends.

ACNOLOGIA has not turned to a good guy. He just learned to be a lot more patient. For all of you who have read the manga and seen the dragon cry movie would know that the dragon king doesn't bother meddling with humans. Both Zeref and Anna Heartfilia mentions this. Zeref even remarks that Acno had the power to rule the world if he wished even with one arm ripped off. He is not a killer and only kills if anyone gets in his path. The only people he bothers is with strong warriors capable of challenging him other than dragons and dragon slayers. He still has no qualms about taking lives. Like I mentioned before, he considers his comrades as his equal and this is the reason for his loyalty and affection towards them and would do anything to ensure their safety .He still despises humans and faunus.

Now about how strong they are?

Gohan is the strongest. Future Gohan can only go upto super saiyan. In his super saiyan form, he is as strong as imperfect cell.

Itachi and Acno are almost equal when overall statistics are considered. Acno wins in terms of sheer power but the Uchiha has got the MS, Amaterasu and the susano o'. So that sort of evens the odds a bit. I know you require etherno to use magic, but I didn't' feel like using that to nerf Acno. So he can use all his magic. The manga did not give any details on what kind of magic he uses. Only a vague idea was given. He is shown as the dragon who devours all magic and is immune to all magic. So I am taking the liberty to assume that he can use all Dragon Slayer magic.

Zack would be the weakest member but is stronger than most other hunters in remnant. He would be strong enough to take down a dragon on his own.

Since we don't know much about Salem's power, all I can say in that matter is that Gohan is definitely stronger than Salem.

Semblances.

The four of them have hidden their powers and only use one specific power that they pass off as their semblances.

Itachi has passed off his semblance to be illusions.

Gohan has passed it off as the ability to channel and modify his aura.

Acnologia's is to change his aura into the 5 elements namely Fire, Water, Wind, Earth and Lightning. His ruse is that he can only do this after he comes in contact with that elemental dust.

Zack's semblance is imitation. He is the only one among them who uses aura and actually has a semblance like the inhabitants of Remnant. His semblance is imitation which allows him to copy and store away any semblance he has seen in action. I based his semblance on his limit breaker 'The digital mind wave'. FF7 fans would know what I am referring to. Currently, he can use two copied semblances simultaneously. The list of semblances in his possession are:

1. Aura sensing ability

2. Teleportation

3. Winter's semblance

4. Shadow clones

5. Telepathic communication

6. Vector: This is his most powerful one. It allows him to change the perception of time of his enemy within a short radius of 10 metre.
